24-Jun-2006 -- This is the most difficult confluence I have done till now.
It is found in a ranch on Pantalan Matogrossense, of difficult acces, with rivers and dense vegetation around the confluence. We tried to get there on June 15, 2006 but we could only get within 2,000 meters.
On the following week, better prepared, went for it again, we walked for more than two hours to cover those 2,000 meters. It was worth it.
